Web26 de mar. de 2024 · In this article is explained how to decrypt a symmetric key. For example: SELECT SK.name, SK.symmetric_key_id, SK.key_length, SK.algorithm_desc, KE.crypt_type_desc, COALESCE(C.name,AK.name,PSK.name) AS protector_name, KE.crypt_property AS encrypted_key, … WebA new symmetric block cipher algorithm called AL02 has been developed. The algorithm scheme provides five-round encryption of 128-bit blocks, while the data size at the input and output of the S-box is 8 bits. The main transformation is the F transformation. The difference between the proposed algorithm and the classical scheme is that the F transformation … 北マリアナ
